If, God forbid, my husband were ever put in a situation anywhere near Terri's (where his mind was forever and irrevocably changed), you can bet your life that I would not be having relations (and children) with other men. When I vowed to stand by my husband, I meant for better or worse, in sickness and in health, until we are parted by death with all my heart and soul. Not any other circumstance. And I would hold him to the same accord were I put in a situation where I was in a conditions similar to Terri's.
I am in awe of your moral certitude....especially in one so young. I'm also curious.....if....God forbid.... your husband were struck with an incurable and terminal condition ...say Lou Gerigh's (I know that isn't spelled correctly!) and he told you he did not want a feeding tube or other mechanical life support....what would you do?

Not argumentative...just curious....
